Re-apply a Parent without duplicating Primary Text Frame?

When you apply a parent page to a document page, all objects on the parent, called parent items, appear on the document page. Sometimes you want a specific page to be only slightly different from a parent. In this situation you don’t need to re-create the parent layout on the page or create a new parent. You can override or detach the parent item, and other parent items on the document page will continue to update with the parent.

Note the difference between overriding and detaching parent items on a document page:

Overriding a parent item puts a copy of it on the document page without breaking its association with the parent page. Once the item itself is overridden, you can selectively override one or more attributes of the item to customize it. For example, you can change the fill color of the local copy. After that, changes to the fill color on the parent page itself will not update to the local copy. However, other attributes, such as size, will continue to update because they have not been overridden on the local copy. Overrides can be removed later to make the object match the parent.

Attributes you can override for a parent page object include strokes, fills, contents of a frame, and any transformations (such as rotating, scaling, shearing, or resizing), corner options, text frame options, lock state, transparency, and object effects.

On a document page, you can detach (disassociate) a parent item from its parent. The item must be overridden on the document page, creating a local copy, before you can detach it. A detached item does not update with the parent because its association with the parent page is broken.
